762. Only one thus far described

The ya-class is the only one thus far described which shows any tendency toward a restriction to a certain variety of meaning. In this tendency, as well as in the form of its sign, it appears related with the class of distinctly defined meaning which is next to be taken up — the passive, with yá-sign. Though very far from being as widely used as the latter beside other present-systems, it is in some cases an intransitive conjugation by the side of a transitive of some other class.
